2 Claims.

This invention relates to certain new and useful improvements in double ring separator for spinning machines.

An object of the invention is to provide a circular separator which acts as a thread guard, guide and a balloon control and is constructed in a manner to permit the use of a lighter traveler than would ordinarily be required resulting in an increase in tension by withholding the balloon as the bobbin increases in diameter.

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing:

Figure 1 is a top plan View of a double ring separator constructed in accordance with the present invention;

Figure 2 is a front elevational view showing the overlapped looped ends of the annular guard; and

Figure 3 is a side elevational view of the separator.

The separator is adapted to be placed in enclosing relation to the upper end of a bobbin and is attached to a supporting rod. The opening in the ring rail for the bobbin being equipped with the usual traveler ring and traveler, such elements being well known in the art.

The double ring separator is formed of resilient wire bent upon itself into double strand formation to provide upper and lower annular guards 5 and 6, the lower annular guard being the intermediate portion of the separator frame wire. The connection between the upper and lower annular guards 5 and 6 includes overlapping looped portions and 8 that constitute guard lips that form guiding means for the entrance throat to the separator. As shown in Figure l, the guard lip 8 projects outwardly of the annular guards 5 and 6 while the terminal end of the guard hp 1 is substantially in the plane of the annular guard. Preferably the wire is square in cross-section, as shown in the drawing, with its edge presented to contact with the yarn.

The opposite side of the upper annular guard 5 diametrically opposite the guide lips I and 8, projects out of the plane of the lower annular guard 6 as shown at 9 in Figure 1 and each portion 9 is bent at right angles as at In to extend transversely across the lower annular guard 6 to provide depending legs, the lower ends of which are angularly bent as at l l to provide anchoring feet for attachment to a supporting rod.

The separator which acts as a balloon control permits the use of a lighter traveler than would ordinarily be required, thereby increasing the tension by withholding the balloon as the bobbin increases in diameter. In other words, the separator acts as a tension evener to counter-act the lessening tension incurred by the increasing diameter of the bobbin. The overlapping arrangement of the guard lips I and 8 retains the thread or yarn within the separator, the separator being especially designed for worsted spinning and in addition to producing a smoother yarn also effects a considerable saving in fly waste by eliminating the batting of the balloon on the windshield type separator.

From the above detailed description of the invention, it is believed that the construction and use thereof will at once be apparent and while there is herein shown and described the preferred embodiment of theinvention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

I claim:-

1. A separator for use in spinning and twisting yarns, said separator being formed of resilient wire bent into a double strand formation comprising approximately annular upper and lower parallel guards connected at one side of the separator by overlapping guard lips, the inner lip tapering toward its end and the end of the outer lip being symmetrically rounded, and attaching legs and angle feet extending from the annular portion of'the separator at points remote from said overlapping lips.

2. A separator for use in spinning and twisting yarns, said separator being formed of resilient wire bent into a double strand formation comprising approximately annular upper and lower parallel guards connected at one side of the separator by overlap-ping guard lips, one of said lips projecting outwardly beyond the circle of said annular portion of the separator and having its end symmetrically rounded and the other lip tapering toward its end, and attaching legs and angle feet extending from the annular portion of the separator at points remote from said overlapping lips.
